Specifically, if I have an @interact, and modify the slider, the content of the page shifts down, obscuring the output of the @interact. The amount of shifting seems to depend on the amount of other cell space below the @interact output. This is using Mac OS X, 10.5.6 and the version of Safari that comes with it. I see the same behavior with FireFox 2.0 (latest version). Is there some configuration foo that I'm missing? I wish. For fun, you might try putting return true; at the top of the function cell_focus in the file devel/sage/sage/server/notebook/js.py and rebuilding sage and restarting the notebook (and refreshing your browser window). All jumping should then be entirely disabled. What does it feel like? Do you like it better? Should this be a trivial-to-set option? I've done the above sometimes when giving talks.

The problem is that the notebook height changes briefly when an interact is updated, which means that the browser automatically scrolls up, but then doesn't scroll back down. A work-around is to create enough empty cells below the interact. A better solution, noted on the trac ticket, is to make a div that is a screen high at the end of the notebook. This would also allow you to have the last cell at the top of the screen, which would be very handy for presentations too. At least MMA lets you scroll down so that the last cell is at the top of the screen.

I was just searching trac too. I can't find anything. The mailing list discussion is here, though (I found this by searching sage-devel for interact jump): http://groups.google.com/group/sage-devel/browse_thread/thread/51b538c8212fa2a/b61655921eb0ebab From the discussion, it looks like a trac ticket never was created (I thought one was). I just created #4963 for it. If this doesn't get done by SD12, I'll try to do it then.

I spent some time debugging this a few months ago, but never did anything about it. Marshall, if you're reading this, this would make a great project for your student if he wants to learn more about html and contribute something quickly.
